VIDEO: 3 Officers Dead, 3 Wounded in Baton Rouge Attack

An ambush shooting in Baton Rouge, LA, killed three police officers and wounded three more early Sunday morning.

A suspect is dead, and two may be at large, according to police.

Police responded to a report of officers shot at a location on Airline Highway near Old Hammond Highway around 9 a.m., reports CBS affiliate WAFB.

The shooting happened near the B Quick store on Airline Highway. Coppola said that authorities believe the "scene is contained," meaning that a shooter was unlikely on the loose.

Sgt. Don Coppola with the Baton Rouge Police Department told WAFB. "We're hearing that it may also include some deputies [with the East Baton Rouge Parish Sheriff's Office], but that's preliminary information and I'm waiting on confirmation."

Baton Rouge has been the scene of protests some of them violent since the July 5 fatal police shooting of Alton Sterling, 37. Sterling’s funeral was held Friday, CBS News reports.

Last week, police arrested and identified three young people who they say plotted to kill Baton Rouge cops using guns stolen from a pawn shop. Law enforcement said at a conference they believe it to be a substantial and credible threat on police officers in the Baton Rouge area.
